' HARROW'.

Specification of Letters Patent. Application filed May 29' 1906- SerialN0.'319 874- Patented Jan. 1, 190?.

1'0 all whom it may concern:

Be it known that I, EUGENE H. PETERS, a citizen of the United States,residing at. Benton Harbor in the county of Berrien and State ofMichigan, have invented certain new and useful Improvements in Harrows;and I do hereby declare the following to be a full, clear, and exactdescription of t e invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to new and useful imrovements in harrows, and moreparticuarly to that class known as disk harrows; and my object is tofirst provide means for conveying the harrow from place to place withoutthe disks thereof engaging the ground.

A further object is to provide means for regulating the depth to whichthe disks enter the ground. 7 l V A still further object is to rovidemeans for extending the disks latera ly on the harrow-frame. v A stillfurther object is to provide means whereby that part of the framecarrying the disks ma be reversed from end to end, thereby 'recting theearth to or from the center of the harrow.

A still further ob'ect is to provide means for disposing said isks' atan angle to the ame. 1

Other ob'ects and advantages will be hereinafter ma e clearly apparentin the specification and pointed out in the claims.

In the accompanging drawings I have shown the referred orm of myinvention.

In said awings, Figure 1 is a top plan view of in improved harrow,showing one set of the 'sks disposed away from the cen ter of the frame.ig. 2 is a rear elevation of my imprroved ,harrow in position to beconveyed om place to place. Fig. 3 is a central longitudinal sectionalview thereof. Fig. 4 is a detail plan view of one set of disks and theframecarrying the same and Fig. 5 is a sectional view as seen from line5 5, Fig. 1.

' Referring to the figures by numerals of reference, 1 indicates themain frame of my -im-' proved harrow, to the under side of which issecured a transversely-disposed bar 2, which is secured to the frame 1-at its center in any preferred manner and is held rigidly in place ymeans of brace-rods 3, said rods extendingfrom the front portion of theframe 1 to the o posite ends of the bars 2 and'are secure thereto bymeans of bolts or the like. Telescopically mounted upon each end of thebar 2 are frames 4 and 5, said frames being provided with channels 8, inwhich is seated the transversely-disposed bar 2. The outer -ends of saidframes 4 and 5 are secured toend sections being preferably formedintegral with the frames, while the opposite ends gether by means of theend sections 9, said thereof are secured together by means of aredisposed at the longitudinal center of the main and auxiliary framessaid auxiliary frames may be turned from end to end and still retaintheir relative positions with the main frame. Secured to the auxiliaframes 11 are de ending brackets 15, said brackets having llbxings 16 attheir lower ends, in which are rotatably mounted shafts 17. A pluralityof cutting-disks 18 are disposed at intervals throughout the length ofsaid shafts .and are rotata lsecured thereon in any preferred manner. 1frames 4 and 5 and the auxiliary-frames 11 are provided with registeringslides or bearing-plates 19 and 20, respectively, said slides beingmounted in pairs and faced against each other so that when saidauxiliary frames are placed at an angle to the main .fr'ames saidauxiliary frames will be held from tilting. The auxiliary frames 11 aredisposed at different angles to the plane of the main frames 4 and5-through the medium of rack-bars 21, carried by the inner ends of themain frames 4 and 5 and with which cooperate the locldng-levers 22, saidlockinglevers having links 23 at their lower ends, said links beingsecured to the auxiliary frames 11 through the medium of bolts 25, saidboltsv being secured to and extending upwardly from the auxiliary frames11. It will therefore be seen that when it is desired to move theauxilia frames out of alinement withthe main ames said result may beaccomplished by moving the levers foriliary frames 11, and as saidplates and bolts ach of the main wardly or rearwardly over the rack-bars21,

said levers and frames being held in their adbe rotated on theking-bolts 12, after whic registering bores in the frames 4 the links 23are again secured to the bolts 25, carried at the opposite ends of theauxiliary frames 11.

In using harrows of this class in orchards or groves of differentclasses it is a diflicult mat ter to cultivate the earth below the treesor bushes, owing to the fact that the limbs prevent the draft-animalsfrom passing thereunder, and to this end I have provided the telescopingframes 4 and 5,.said frames being so arranged that when it is desired tocultivate ground below the trees or bushes the frames carrying the disksmay be moved outwardly on the transversely-disposed bar 2, as best showninFig. 1 of the drawings, thereby disposing the cutting-disks to oneside of the draftanimals, so that said disks will be disposed so as topass below the limbs of the trees or bushes and cultivate the oundthereunder. The frames '4 and 5 are position upon the transverse bar 2by means of pins 27, said pins being disposed through and 5 and thetransversely disposed bar 2. The front end of the main frame 1 isprovided with a swivel-coupling 28, through which extends a squaredshaft 29, said shaft having an axle 30 at its lower end, upon theopposite ends of which are mounted su porting-wheels 31. The axle 30 isalso provi ed with a forwardly and upwardl extending shank 32, whichpasses throug a projection 33 on the swivelcou ling 28 and is providedin its length with a p ur-a ity of o enin s 34. A tongue 35 is disposedaroun the s ank 32 and is adjustably secured thereto by means of a pin36,

I takin through any one of the openings 34 and t on h a similar openingin the tongue 35. The eight of the forward end of the frame 1 upon theshaft 29 is regulated b mea us of a set-screw 37, which asses throughthe swivel 28 and engages the shaft 29 so that when the frame 1 has beenelevated to the (proper height the set-screw is turned inwar ly until itengages the shaft 29 and holds said frame in its adjusted position. By

having the forward part of the truck arranged as described andsecured-to the frame of the harrow by means of the swivel 28 it will beseen that the strain u on' the tongue incident to the turning of thearrow will be dis ensed with and the harrow caused to turn t rou h themedium of the draft upon the doub etrees.

eld in .bar, right-angled extensions ri A larger pair of wheels 38 aredisposed at the opposite end of the frame 1, said wheels being mounted uon an axle 39, which is in turn carried by a h a pair ofupwardly-extending bars 41, which are disposed through suitable ways 42in the frame 1 and are connected at their upper ends by means of thecross-head 43, said crosshead having rack-teeth 44 on the up er edgethereof. head 43 is a lever 45, said lever having a spring-controlledlatch 46, adapted to enage with the teeth upon the rack-bar 44.

he lower end of the ever 45 is bifurcated and has that portion of itsbifurcated ends beyond its pivot-point directed at right angles to themain portion of the lever and is pivotally connected to the frame 1 bymeans of a substantially U-shaped link 47, so that when the lever 45isdisposed in the position shown in Fig. 3 of the drawings the disks 18will .be dis osed out of engagement with the earth an from one place toanother. When, however, it is desired to cultivate the ground, the lever45 is moved to the opposite side of the rack bar 44, thereby loweringthe frame 1 until the disks 18 are in en agement with the earth, and thedepth to w 'ch said disks may enter the earth is controlled by means ofsaid lever, rack-bar, and link, it being understood'that the higher therear end of the frame 1 is elevated on the bars 41 the less the earthwillbe disturbed by the disks. A seat 48 is disosed upon the frame 1 andin reach of the evers 22 and 45, so that the operator can control saidlevers when in their normal positions without dismounting from theharrow.

What I claim is 1. A harrow of the class described comprising a frame orbody portion, a transverse bar ri id with said body portion, channeledframes telescopically mounted on said bar, auxiliary frames below saidchanneled frames, plates on said channeled and auxiliary frames havingregistering bores, bolts disposed through sa1d bores to rotatably securesaid auxiliary frames to said channeled frames, a plurality of diskscarried by said auxiliary frames and means carried by the channeledframes to vary thepath of said disks.
